You can upload a resource file. Basically any valid file can be uploaded... Html, Images etc.
Open the report manager interface (http://yourservername/reports by default)
Click the "Upload" menu item (it's up top)
Browse to the file you want to upload, click OK.

After performing more research, it looks like even though the file we are uploading are valid HTML documents, SSRS is no longer interpreting them as the correct MIME Type.
Previously SSRS would see these as Text/HTML so when you clicked on the HTML document it would open in your browser like any other URL link/shortcut etc.
After applying 2016 SP2, when I upload the same HTML document it shows as MIMEtype application/octet-stream - This is available from the properties window. When you click the hyperlink it tries to download the file instead of opening it in a browser window.
I'm not certain if this is an improved security "feature" or a bug. I didn't see this documented in the Service pack release notes and I didn't see anything on the SQL Server User voice site, but I may have missed it, which is why I'm reaching out here, to see if anyone else has seen this and if they have any workarounds.
The best work around I've found so far is to create a report with URL hyperlinks in the report. We want our users to be able to open our Data Dictionary website (created using SQLDoc!) from within SSRS Report Manager so they don't have to remember another link.Thanks,
